I installed 4.2.1, but all scripts using ImagePNG() crashed. Apache generates this message: [Fri Jun 7 10:01:25 2002] [notice] child pid 28042 exit signal Segmentation fault (11) I tested same imagescripts with ImageJPEG(), and everything works fine... Since this is an production server, i had to install 4.1.2 back (there's no problems with 4.1.2), and couldn't test things more... my conf is: ./configure --with-apache=../apache_1.3.24 \ --enable-track-vars \ --with-mysql \ --enable-ftp \ --enable-sockets \ --with-zlib-dir=shared \ --with-zip=/usr/local/lib \ --with-gd=/home/tux/filez/gd-2.0.1 \ --with-pdflib=/usr/local/lib \ --with-freetype-dir=/usr/local/lib \ --with-t1lib=/usr/local/lib \ --enable-gd-native-ttf \ --with-jpeg-dir=/usr/local/lib \ --with-png-dir=/usr/local/lib \ --with-tiff-dir=/usr/local/lib \ --with-openssl \ --with-curl=/usr/local/lib \ --with-mcrypt=/usr/local/lib \ --enable-ctype \ --enable-exif \ im using libpng 1.2.1, zlib 1.1.4, jpeg-6b, gd 2.0.1, freetype 2.0.9 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17659&edit=1
